OPP-10 octylphenol polyoxyethylene ether phosphate is an anionic phosphate ester surfactant, appearing as a light yellow to yellow viscous liquid. This product is irritating to skin and eyes, combustible when exposed to open flames or high heat, and may release toxic phosphorus oxide gases upon thermal decomposition. In addition, it is highly toxic to aquatic life with long-lasting effects. Therefore, strict safety regulations must be followed during storage, use, and disposal.
Operators must undergo specialized training and work in enclosed or well-ventilated environments. Keep away from sparks and heat sources; smoking is strictly prohibited in the workplace. Avoid contact with oxidizers and strong alkalis during operation. Handle with care during transportation to prevent damage to packaging and containers. It is recommended to equip safety showers and eyewash stations to handle emergencies.
In case of leakage, immediately evacuate personnel from the contaminated area to a safe zone, isolate the area, restrict access, and eliminate all ignition sources. For small spills, cover and collect with inert absorbent materials such as sand, vermiculite, etc. For large spills, dike far ahead to contain the spill and transfer with explosion-proof pumps. Under no circumstances should the product be allowed to enter sewers, surface water, or groundwater.
| Protective Area | Protective Measures |
|---|---|
| Respiratory system | When potentially exposed to vapors or fumes, wear a filter-type gas mask (half-face); in emergency or evacuation situations, wear an air respirator. |
| Eyes | Wear chemical safety goggles. |
| Body | Wear impermeable protective clothing to avoid skin contact. |
| Hands | Wear chemical-resistant protective gloves, such as nitrile rubber gloves. |
| Exposure Type | First Aid Method |
|---|---|
| Skin contact | Immediately remove all contaminated clothing and thoroughly rinse skin with plenty of running water and soap. If irritation symptoms occur, seek medical attention immediately. |
| Eye contact | Immediately lift eyelids and rinse continuously with plenty of running water or saline for at least 15 minutes. Seek medical attention immediately. |
| Inhalation | Quickly remove from the scene to fresh air and maintain an open airway. If breathing is difficult, administer oxygen. If breathing or heartbeat stops, immediately perform CPR. Seek medical attention immediately. |
| Ingestion | Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Seek medical attention immediately. |
This product is combustible when exposed to open flames or high heat; thermal decomposition releases toxic phosphorus oxide and carbon oxide fumes. Firefighters must wear full-body fireproof and chemical protective clothing and operate from upwind or a safe distance. Suitable extinguishing agents: alcohol-resistant foam, dry powder, carbon dioxide, sand/earth.
